Homicidal Ideation
Homicidal ideation is a common medical term for thoughts about homicide. There is a range of homicidal thoughts which spans from vague and fleeting to detailed and fully formulated plans without the act itself. Most people who have homicidal ideation do not commit homicide. 50–91% of people surveyed on university grounds in various places in the United States admit to having had a homicidal fantasy. Homicidal ideation accounts for 10–17% of patient presentations to psychiatric facilities in the United States. Homicidal ideation is not a disease itself, but may result from other illnesses such as delirium and psychosis. Psychosis, which accounts for 89% of admissions with homicidal ideation in one US study, includes substance-induced psychosis (e.g. amphetamine psychosis) and the psychoses related to schizophreniform disorder and schizophrenia. Delirium is often drug induced or secondary to general medical illness(es). It may arise in association with personality disorders o ...

Psychiatry
Psychiatry is the medical specialty devoted to the diagnosis, treatment, and prevention of deleterious mental disorder, mental conditions. These include matters related to cognition, perceptions, Mood (psychology), mood, emotion, and behavior. Initial psychiatric assessment of a person begins with creating a Medical history, case history and conducting a mental status examination. Laboratory tests, physical examinations, and psychological tests may be conducted. On occasion, neuroimaging or neurophysiological studies are performed. Mental disorders are diagnosed in accordance with diagnostic manuals such as the ''International Classification of Diseases'' (ICD), edited by the World Health Organization (WHO), and the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM), published by the American Psychiatric Association (APA). The fifth edition of the DSM (DSM-5) was published in May 2013. Treatment may include psychotropics (psychiatric medicines), psychotherapy, su ...

Hallucination
A hallucination is a perception in the absence of an external stimulus that has the compelling sense of reality. They are distinguishable from several related phenomena, such as dreaming ( REM sleep), which does not involve wakefulness; pseudohallucination, which does not mimic real perception, and is accurately perceived as unreal; illusion, which involves distorted or misinterpreted real perception; and mental imagery, which does not mimic real perception, and is under voluntary control. Hallucinations also differ from " delusional perceptions", in which a correctly sensed and interpreted stimulus (i.e., a real perception) is given some additional significance. Hallucinations can occur in any sensory modality— visual, auditory, olfactory, gustatory, tactile, proprioceptive, equilibrioceptive, nociceptive, thermoceptive and chronoceptive. Hallucinations are referred to as multimodal if multiple sensory modalities occur. A mild form of hallucination is known as ...

Lust
Lust is an intense desire for something. Lust can take any form such as the lust for sexuality (see libido), money, or power. It can take such mundane forms as the lust for food (see gluttony) as distinct from the need for food or lust for redolence, when one is lusting for a particular smell that brings back memories. It is similar to but distinguished from passion, in that properly ordered passion propels individuals to achieve benevolent goals whilst lust does not. In religion Religions tend to draw a distinction between passion and lust by further categorizing lust as an immoral desire and passion as morally accepted. Lust is defined as immoral because its object or action of affection is improperly ordered according to natural law and/or the appetite for the particular object (eg sexual desire) is governing the person's will and intellect rather than the will and intellect governing the appetite for that object. Whereas passion, regardless of its strength, is maintaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revenge
Revenge is defined as committing a harmful action against a person or group in response to a grievance, be it real or perceived. Vengeful forms of justice, such as primitive justice or retributive justice, are often differentiated from more formal and refined forms of justice such as distributive justice or restorative justice. Function in society Social psychologist Ian Mckee states that the desire for the sustenance of power motivates vengeful behavior as a means of impression management: "People who are more vengeful tend to be those who are motivated by power, by authority and by the desire for status. They don't want to lose face". Vengeful behavior has been found across a majority of human societies throughout history. Some societies encourage vengeful behavior, which is then called a feud. These societies usually regard the honor of individuals and groups as of central importance. Thus, while protecting their reputation, an avenger feels as if they restore the pre ...

Jealousy
Jealousy generally refers to the thoughts or feelings of Emotional insecurity, insecurity, fear, and concern over a relative lack of possessions or safety. Jealousy can consist of one or more emotions such as anger, resentment, inadequacy, helplessness or disgust. In its original meaning, ''jealousy'' is distinct from envy, though the two terms have popularly become synonymous in the English language, with ''jealousy'' now also taking on the definition originally used for envy alone. These two emotions are often confused with each other, since they tend to appear in the same situation. Jealousy is a typical experience in Interpersonal relationship, human relationships, and it has been observed in infants as young as five months.Draghi-Lorenz, R. (2000). Five-month-old infants can be jealous: Against cognitivist solipsism.

Narcissistic Personality Disorder
Narcissistic personality disorder (NPD) is a personality disorder characterized by a life-long pattern of grandiosity, exaggerated feelings of self-importance, an excessive need for admiration, and a diminished ability to empathy, empathize with other people's feelings. It is often comorbid with other mental disorders and associated with significant functional impairment and psychosocial disability. Personality disorders are a class of mental disorders characterized by enduring and inflexible maladaptive patterns of behavior, cognition, and inner experience, exhibited across many contexts and deviating from those accepted by any culture. These patterns develop by early adulthood, and are associated with significant distress or impairment. Criteria for diagnosing personality disorders are listed in the sixth chapter of the ''International Statistical Classification of Diseases and Related Health Problems, International Classification of Diseases'' (ICD) and in the American Psyc ...

Conduct Disorder
Conduct disorder (CD) is a mental disorder diagnosed in childhood or adolescence that presents itself through a repetitive and persistent pattern of behavior that includes theft, lies, physical violence that may lead to destruction, and reckless breaking of rules, in which the basic rights of others or major age-appropriate norms are violated. These behaviors are often referred to as " antisocial behaviors", and is often seen as the precursor to antisocial personality disorder; however, the latter, by definition, cannot be diagnosed until the individual is 18 years old. Conduct disorder may result from parental rejection and neglect and in such cases can be treated with family therapy, as well as behavioral modifications and pharmacotherapy. It may also be caused by environmental lead exposure. Conduct disorder is estimated to affect 51.1 million people globally Signs and symptoms One of the symptoms of conduct disorder is a lower level of fear. Research performed on th ...

Mental Disorder
A mental disorder, also referred to as a mental illness, a mental health condition, or a psychiatric disability, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. A mental disorder is also characterized by a clinically significant disturbance in an individual's cognition, emotional regulation, or behavior, often in a society, social context. Such disturbances may occur as single episodes, may be persistent, or may be relapsing–remitting. There are many different types of mental disorders, with signs and symptoms that vary widely between specific disorders. A mental disorder is one aspect of mental health. The causes of mental disorders are often unclear. Theories incorporate findings from a range of fields. Disorders may be associated with particular regions or functions of the brain. Disorders are usually Medical diagnosis, diagnosed or assessed by a mental health professional, such as a Clinical psychology#Profes ...

Head Injury
A head injury is any injury that results in trauma to the skull or brain. The terms ''traumatic brain injury'' and ''head injury'' are often used interchangeably in the medical literature. Because head injuries cover such a broad scope of injuries, there are many causes—including accidents, falls, physical assault, or traffic accidents—that can cause head injuries. The number of new cases is 1.7 million in the United States each year, with about 3% of these incidents leading to death. Adults have head injuries more frequently than any age group resulting from falls, motor vehicle crashes, colliding or being struck by an object, or assaults. Children, however, may experience head injuries from accidental falls or intentional causes (such as being struck or shaken) leading to hospitalization. Acquired brain injury (ABI) is a term used to differentiate brain injuries occurring after birth from injury, from a genetic disorder, or from a congenital disorder. Unlike a broken bo ...

Frontal Lobe
The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe). It is parted from the parietal lobe by a Sulcus (neuroanatomy), groove between tissues called the central sulcus and from the temporal lobe by a deeper groove called the lateral sulcus (Sylvian fissure). The most anterior rounded part of the frontal lobe (though not well-defined) is known as the frontal pole, one of the three Cerebral hemisphere#Poles, poles of the cerebrum. The frontal lobe is covered by the frontal cortex. The frontal cortex includes the premotor cortex and the primary motor cortex – parts of the motor cortex. The front part of the frontal cortex is covered by the prefrontal cortex. The nonprimary motor cortex is a functionally defined portion of the frontal lobe. There are four principal Gyrus, gyri in the frontal lobe. The precentral gyrus is directly anterior to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antisocial Personality Disorder
Antisocial personality disorder (ASPD) is a personality disorder defined by a chronic pattern of behavior that disregards the rights and well-being of others. People with ASPD often exhibit behavior that conflicts with social norms, leading to issues with interpersonal relationships, employment, and legal matters. The condition generally manifests in childhood or early adolescence, with a high rate of associated conduct problems and a tendency for symptoms to peak in late adolescence and early adulthood. The prognosis for ASPD is complex, with high variability in outcomes. Individuals with severe ASPD symptoms may have difficulty forming stable relationships, maintaining employment, and avoiding criminal behavior, resulting in higher rates of divorce, unemployment, homelessness, and incarceration. In extreme cases, ASPD may lead to violent or criminal behaviors, often escalating in early adulthood. Research indicates that individuals with ASPD have an elevated risk of suicide, ...
